[0032] The present invention is described in detail below by means of exemplary embodiments. However, it should be understood that, without further description, elements, structures and features in one embodiment may also be beneficially combined in other embodiments.

[0033] It should be noted that, unless otherwise defined, the technical terms or scientific terms used herein shall have the usual meanings understood by persons with ordinary skills in the field to which the invention belongs. The words "one", "an" or "the" and the like used in the patent application specification and claims of the present invention do not express quantitative limitations, but indicate the existence of at least one. Words such as "include" or "comprise" indicate that the elements or objects appearing before "include" or "comprises" include the elements or objects listed after "include" or "comprises" and their equivalents, but do not exclude other elements or objects with the same function.

[0034] Here, the cutting of seed potatoes is first explained. As shown in the figure, the seed potato cutting process of this scheme adopts a longitudinal cutting method along the long axis 103 of the potato 100 to divide it into two, thereby cutting it into seed potato block Ⅰ101 and seed potato block Ⅱ102. Since the outer skin of the seed potato is irregular, most of them are cut into these two types of seed potato blocks. The outer curvature of seed potato block Ⅰ101 is flat as shown in the figure 1032, and its cutting surface Ⅰ is shown in Figure 1301; the outer curvature of seed potato block Ⅱ102 is convex as shown in the figure 1034, and its cutting surface Ⅱ is shown in Figure 1033.

[0035] As shown in the figure, the present scheme provides a potato sprout sowing device, comprising a seed box 1 and a sprout conveyor belt 2 located below the seed box 1, wherein the seed box 1 is arranged at the input end of the sprout conveyor belt 2, and the input end of the sprout conveyor belt 2 is connected with the lower seed opening of the seed box 1, and the inner cavity of the seed box 1 is used to store a large number of cut seed potatoes, and a seed stirring mechanism is arranged on the side wall of the seed box 1, and the seed stirring mechanism comprises a seed stirring motor 11 and a seed stirring member 12, and the seed stirring member 12 is installed on the output shaft of the seed stirring motor 11 and is located at the circular notch of the side wall of the seed box 1, and the seed stirring member 12 comprises a connecting shaft 121 and a seed stirring plate 122, wherein the center of the first end face of the seed stirring plate 122 is vertically connected to the connecting shaft 121, and the second end face of the seed stirring plate 122 is not parallel to the first end face, and the seed stirring plate 122 is a round cake structure with one side thick and the other side thin. 122 is installed on the side wall of the seed box 1, and one side of the seed stirring plate 122 will protrude inward from the inner wall of the seed box 1, forming a smooth transition at the transition position between the surfaces. Therefore, the seed stirring plate 122 is not easy to damage the seeds during the stirring process. In order to further prevent the seeds from being damaged during the stirring process, the seed stirring plate 122 can be made of a flexible material, such as a rubber block or coated with a flexible material. During the stirring process, the stirring block 122 can continuously change the stacking state of the seed potatoes in the seed box 1 by utilizing its unique structure, thereby preventing the seed potatoes from clogging up. By controlling the rotation of the seed stirring motor 11 to drive the seed stirring member 12, dynamic seed supply of seed potato blocks is realized, effectively preventing the seed potatoes from clogging up in the seed box 1, and stably falling on the positive bud conveyor belt 2. The bottom plate at the lower seed opening of the seed box 1 is an inclined surface, which is conducive to the smooth seeding of the seed box 1.

[0036] like Figure 4 As shown, the positive bud conveying motor 26 is fixed at the bottom of the positive bud conveyor belt 2, and the upper and lower conveying surfaces of the positive bud conveyor belt 2 are parallel. The conveying surface of the positive bud conveyor belt 2 that fits the seed potato pieces has two side edges in the horizontal direction, wherein one side edge (the first side) is higher than the height of the other side edge (the second side), so the positive bud conveyor belt forms a certain downward slope along the first direction E, and the first direction E refers to the direction from the first side of the positive bud conveyor belt to the second side. The conveying surface of the positive bud conveyor belt 2 forms a certain inclination angle A relative to the horizontal reference plane D, and in particular, a retaining edge 23 is provided on the side where the conveying surface is at a lower position. The positive bud conveyor belt 2 includes a positive bud section 21 near the input end and a broken line section 22 near the output end, wherein the inclination slope of the positive bud section 21 with the horizontal reference plane D is 15-25°. Through this inclination design, the positive bud conveyor belt 2 can be used to screen out the seed potato pieces in non-positive bud positions due to the small contact area between the positive bud conveyor belt 2 and the seed potato pieces.

[0037] In this solution, the function of the baffle 23 is to prevent the seed potato pieces in the positive bud state from sliding off the conveyor belt, and not to affect the seed potato pieces in the non-positive bud state from detaching from the conveyor belt. The sidewall 23 has the following implementation methods: The first implementation method is that the sidewall 23 is parallel to the horizontal reference plane D in the figure, and the sidewall 23 is designed as an integral part of the conveyor belt. The width of the sidewall 23 can only support and block the seed potato pieces in the positive bud state. As for the seed potato pieces in the non-positive bud state, due to the limited space on the sidewall 23, the seed potato pieces in the non-positive bud state will roll or slide to the sidewall 23 under the inclined surface of the positive bud conveyor belt 2, and then fall into the collection box (not shown in the figure) below the positive bud conveyor belt 2. The collection box is used to collect the fallen seed potato pieces in the non-positive bud state. When the collection box is full, it can be poured back into the seed box 1. The angle between the sidewall 23 and the horizontal reference plane D is set to zero, or slightly has a certain downward inclination angle, and the sidewall 23 is set as an integral part of the conveying surface of the positive bud conveyor belt 2. The retaining edge 23 can prevent the seed potato pieces after sprouting from falling on the sprouting conveyor belt 2, and realize the sprouting engineering of the seed potato pieces. For the seed potatoes in the non-sprouting state that fall into the retaining edge 23, the slight downward inclination angle can better make such seed potatoes fall off smoothly. The second implementation method is: the retaining edge 23 includes a horizontal step and an outer plate with a certain downward inclination angle. The horizontal step is used to prevent the seed potatoes in the sprouting state from sliding down, so the width of the horizontal step is narrow. The outer plate has a downward inclination relative to the horizontal reference surface D. The function is to automatically slide the seed potatoes in the non-sprouting position that fall on the retaining edge from the outer plate and fall off and enter the collection box, so as to achieve the screening of the seed potatoes in the non-sprouting position.

[0038] In this solution, when the seed potato block I 101 and the seed potato block II 102 are in contact with the positive bud conveyor belt 2, when the outer cambered surface of the seed potato block I 101 and the seed potato block II 102 is in contact with the conveyor belt surface, since the outer skin of the seed potato block II 102 is relatively convex, the contact area with the positive bud conveyor belt 2 is small, and therefore the sliding friction is small. When it is in a non-positive bud state (the outer cambered surface of the seed potato block II 102 is in contact with the conveyor surface), it is easy to roll or slide on the inclined surface of the positive bud section 21 to the retaining edge 23, and fall off the conveyor belt into the collection box. For the seed potato block I 101, the skin is relatively flat, and the contact area with the conveyor belt surface is large, so the friction is large. When it is in a non-positive bud state (the outer cambered surface of the seed potato block I 101 is in contact with the conveyor belt surface), the outer skin of the seed potato block I 101 is relatively flat, and the contact area with the conveyor belt surface is large. Therefore, the friction is large. Belt contact), it may still be difficult to roll or slide down the inclined surface of the positive bud section 21. Therefore, the seed potato pieces Ⅰ101 in the non-positive bud posture may not be completely screened out in the positive bud section. In this way, when this type of seed potato pieces Ⅰ101 runs to the corner, as the contact area becomes smaller, the seed potato pieces will roll or slide down, thereby further screening out this type of seed potato pieces in the non-positive bud state. Since the cutting surface of the seed potato pieces in the positive bud state has good contact with the conveying surface and the inclination angle of the conveying surface is limited, the seed potato pieces in the positive bud state will not slide down, or a small part of them will be intercepted by the retaining edge 23 after sliding down, and the cutting surface of this type of seed potato pieces is still in contact with the conveying surface, so they are still in the positive bud state.

[0039] In this solution, since the positive bud conveyor belt is provided with two sections, a folded angle is formed in the transition zone between the folded line section 22 and the positive bud section 21, the purpose is as described above: to reduce the contact surface between the conveyor belt and the seed potato cut pieces at the folded angle of the transition zone, at this time, the seed potato pieces Ⅰ101 corresponding to the flat outer skin will roll or slide down along the conveyor belt surface due to the reduction of the contact surface, and thus detach from the conveyor belt at the baffle 23 to screen out such potato cut pieces. Although most of the potatoes in the non-positive bud state on the sidewall 23 will detach, it is not ruled out that a small number of potatoes in the non-positive bud state will not be completely detached at the sidewall 23, so an arc baffle 25 is provided at the output end of the folded line section 22, and the arc baffle 25 has an arc structure bent inward at one end facing the positive bud conveyor belt 2. As the conveyor belt moves, the arc structure is used to peel off and eject the excess seed potato cut pieces that have not completely detached from the sidewall 23 so as to enter the collection box. The positive bud conveyor belt 2 of this solution provides a basis for subsequent positive bud sowing.

[0040] The present embodiment further comprises a groove conveyor belt 3. The function of the groove conveyor belt 3 is to realize the interval positioning and sorting of disordered seed potato pieces with positive buds. The structure of the groove conveyor belt 3 is as follows: the groove conveyor belt 3 comprises a base frame 33 and a groove transmission motor 35 and a conveyor belt 32 arranged on the base frame 33. A row of seed grooves 31 are arranged on the belt surface of the conveyor belt 32 along its annular length direction, and the number of the seed grooves 31 is preferably 10-30. The seed grooves 31 are used for positioning and placing the seed potato pieces.

[0041] In this solution, a position correction component 4 is arranged above the groove conveyor belt 3. The position correction component 4 is arranged on the input end side of the groove conveyor belt 3. The function of the position correction component 4 is to sweep the seed potato pieces falling into the outer side of the seed groove 31 into the seed groove 31. In this solution, the seed potato pieces can be correctly sorted for buds and accurately sown through the correct bud conveyor belt 2, the groove conveyor belt 3 and the baffle component 4, thereby achieving the effect of correct bud sowing and improving the sowing efficiency.

[0042] The correction component 4 of this scheme includes a correction plate 41, a column 43 and a flexible brush 42. The first implementation method of the correction plate 42 is a flat straight plate. The correction plate 42 is arranged in a direction perpendicular to the seed feeding direction of the conveyor belt 32. The two sides of the correction plate 42 are fixed to the base frame 33 through the columns 43. The flexible brush 42 is made of nylon material to avoid damage to the seed potatoes. The flexible brush 42 is fixedly arranged on the correction plate 42 and extends downward. This structure has a better correction effect on the seed potatoes that fall into the front and rear sides of the seed trough 31 along the conveying method, and it is easy to sweep the seed potato pieces into the seed trough 31 through the cooperation of the flexible brush 42 and the conveyor belt 32. However, it is difficult to push the seed potato pieces that fall into the left and right sides of the seed trough 31 into the seed trough 31. Therefore, we designed a second implementation method of the correction plate 41. The structure of the second correction plate 41 is as follows: the cross section of the correction plate 41 is V-shaped, wherein the opening side of the V-shaped correction plate 41 faces the side direction of the conveyor belt 32, the side direction refers to the head end direction of the groove conveyor belt 3, the tip side of the V-shaped correction plate 41 faces the tail end direction of the groove conveyor belt 3, and the bending tip of the V-shaped correction plate 41 is located directly above the running track of the groove 31, and the flexible brush 42 is arranged on the correction plate 41 and extends downward, wherein the flexible brush 43 is connected to the groove conveyor belt 3 The gap of the conveying surface should be smaller than the size of a single seed potato piece. The purpose is to block the seed potato pieces from passing through the outside of the seed trough 31 through the lower end of the flexible brush 43. The V-shaped correction plate 41 can not only push the seed potato pieces falling into the front and rear sides of the seed trough 31 in the conveying direction into the seed trough 31, but also help to block the seed potato pieces located on the left and right sides of the conveying direction of the seed trough 31. Under the joint action of the groove conveyor belt 3 and the flexible brush 42, the seed potatoes outside the trough that fall into the left and right sides of the seed trough 31 are gradually pushed into the seed trough 31.

[0043] The present solution is further provided with an inertial seeding mechanism 6, which is mounted on a base frame 33 on one side of the output end of the groove conveyor belt 3, and a seeding channel 61 is connected with the seed slot 31 at the end of the groove conveyor belt 3 for seeding, and the seeding channel 61 has an input end and an output end, wherein the input end of the seeding channel 61 is connected with the seed slot 31 of the groove conveyor belt 3, and the seeding channel 61 is driven by the inertial seeding mechanism 6 to reciprocate back and forth along the seed feeding direction of the groove conveyor belt 3, and realizes docking and separation actions with the end of the groove conveyor belt 3, thereby realizing inertial seeding.

[0044] The structure of the seeding channel 61 is analyzed as follows: the seeding channel 61 includes a horizontal section 611 and an inclined section 612, and a smooth transition is adopted between the horizontal section 611 and the inclined section 612. The horizontal section 611 is close to the input end of the seeding channel 61, and is basically in the same plane as the horizontal reference plane D, and is used to connect with the seed groove 31 running to the tail end of the groove conveyor belt 3. The inclined section 612 has a gradually downward slope toward the seeding port side, the purpose is to ensure that the seed potato blocks in the inclined section 612 are smoothly seeded along the inclined downward angle. A seed protection spring plate 613 is arranged in the seeding channel 61, and the first end of the seed protection spring plate 613 is fixed to the seeding channel. At the entrance of channel 6, the second end of the seed protection spring plate 612 is a free end and extends to the seed discharge port of the seed discharge channel 61, the purpose is to ensure that the posture of the seed potato maintains the correct bud posture during the sliding process. The seed protection spring plate 613 has a shape with the same amplitude as the bottom plate of the seed discharge channel 6, and a seed discharge channel space for the seed potato is formed between the seed protection spring plate 612 and the bottom plate of the seed discharge channel 61, which can just accommodate one seed potato to pass through. Since the second end of the seed protection spring plate 613 is in a free state, it ensures that the seed protection spring plate 613 has a certain elastic effect, which can not only ensure the free fall of the seed potato, but also has a certain elastic force that is conducive to maintaining the correct bud posture of the seed potato.

[0045] The structure of the inertial seeding mechanism is analyzed as follows: the inertial seeding mechanism 6 includes a seeding channel 61, a seeding motor 62, a fixed frame 63, a telescopic frame 64 and a spring 65. The fixed frame 63 includes two oppositely arranged vertical frames 631 spanning across the base frame 33. The motor frame 67 is connected to the fixed frame 63 by welding, bolts or integrally formed. The motor frame 67 is used to fix the base of the seeding motor 62. The fixed frame 63 includes a vertical frame and a connecting frame. A connecting frame is arranged across the two vertical frames. The connecting frame has a vertical rod and a horizontal rod. The two ends of the horizontal rod are respectively vertically connected to the vertical rod and fixed to the vertical frame through the vertical rod. The vertical rod of the connecting frame is provided A sliding hole is provided through which a telescopic frame 64 passes. The telescopic frame 64 includes a telescopic rod and a mounting frame 68 located at one end of the telescopic rod. The seeding channel 61 is arranged below the mounting frame 68. The telescopic rod is an integrated rod-shaped structure with smooth sections 641 at both ends and a rack section 642 in the middle. The smooth sections 641 at both ends are respectively slidably arranged in the sliding holes of the fixing frame 63. The cross-section of the smooth section 641 at one end is circular and is used to install the spring 65. The smooth section 641 at the other end is triangular, rectangular or polygonal. The smooth section 641 of such shape cooperates with the sliding hole to prevent the telescopic frame 64 from twisting around the axis. The rack section 642 is arranged on the seeding electric The seeding motor 62 is driven to reciprocate back and forth, and the seeding motor 62 is installed on one side of the fixed frame 63. The running speed of the seeding motor 62 is designed to correspond to the running speed of the groove conveyor belt 3, so as to achieve the coordination between the two. A missing gear 66 is fixed on the output shaft of the seeding motor 62. The outer edge of the missing gear 66 includes a missing tooth segment and an outer tooth segment. The outer tooth segment of the missing gear 66 can mesh with the rack segment 642 of the telescopic frame 64. The output shaft of the seeding motor 62 rotates one circle, which can drive the outer teeth of the missing gear 66 to mesh with the rack segment of the telescopic rod 641 once, thereby driving the seeding channel 61 close to one side of the groove conveyor belt 3, so as to move the groove conveyor belt 3 The seed potatoes in the seeding channel 61 are smoothly sent into the seeding channel 61. A spring 65 is inserted on the smooth section 641 of the telescopic frame 64 near one side of the seeding channel 61. One end of the spring 65 is in contact with the fixed frame 63, and the other end is in contact with the mounting frame 68. The purpose is that when the toothed section of the missing gear 66 is opposite to the rack section 642 of the telescopic rod, the missing gear 66 is out of contact with the rack section 642. The elastic potential energy of the spring 65 due to the movement of the telescopic frame 64 to the side of the groove conveyor belt 3 will be released, and the seeding channel 61 will pop outward under the action of the elastic potential energy of the spring 65, thereby realizing the smooth seeding of the seed potatoes and finally realizing the positive bud sowing. This solution realizes inertial sowing, fertilization, and seed potato coating under the driving and transmission action of the spring 65, the missing gear 66, and the telescopic frame 64.

[0046] In this solution, considering that the coating work of the cut edges of the seed potato pieces is completed while the seeds are being sown, a coating box 64 is provided in the middle section of the bottom plate of the inclined section 612 of the seeding channel 61, and a hole is formed on the bottom plate of the seeding channel 61 on the upper surface of the coating box 64. The coating box 64 can be used to contain plant ash. The hole 618 on the bottom plate of the inclined section 612 can be used to smoothly discharge the plant ash into the seeding channel 61 under the action of inertia, and the seed potato pieces passing through the seeding channel 61 are coated with plant ash, so that the cut surfaces of the potato pieces are wrapped with plant ash powder, and the amount of plant ash can also be saved, which is beneficial to the growth of potato pieces. The shape and section of the coating box 64 can adopt the structure shown in the figure, the bottom plate of the coating box 64 is basically kept horizontal with the horizontal reference plane D, and the bottom of the coating box 64 is designed horizontally, which can ensure that the plant ash in the coating box 64 is always horizontally laid, so that the plant ash is wrapped more evenly at the bottom of the potato pieces, and the waste of plant ash is reduced. The ash is discharged smoothly into the seeding channel 61 under the action of inertia. The seeding channel 61 will pop out to the side away from the groove conveyor belt 3 under the action of the elastic potential energy of the spring 65. When the seeding channel 61 is in place, the ash will enter the seeding channel 61 through the hole under the action of its inertia. When the seed potatoes pass through the seeding channel 61, the seed potato pieces will adhere to the ash, so that they can be smoothly coated during the seeding process to reduce the pest rate.

[0047] In order to fertilize while planting seeds, a fertilizer box 5 is arranged above the groove conveyor belt 3, and liquid fertilizer is contained in the fertilizer box 5. The first method is: a fertilizer port 52 is arranged at the bottom of the fertilizer box 5, and the fertilizer port 52 is provided with an openable and closable baffle 51. The baffle 51 can be automatically controlled by a telescopic motor to control the opening and closing of the baffle at a fixed time interval so as to perform interval fertilization. The second method is: a control switch is arranged at the discharge pipe of the fertilizer port 52, and the discharge pipe is connected to the fertilizer hose 616 through the fertilizer hose 616. The fertilizer channel 615 of the seeding channel 61 is connected, so as to control the communication between the feeding pipe and the fertilizer box 5 at intervals. The third method is: as shown in the figure, a fertilizer port 52 is provided at the bottom of the fertilizer box 5, and the fertilizer port 52 is provided with an openable baffle 51, which is connected to one end of the telescopic frame 64. The baffle 51 can also be driven by the telescopic frame 64 to open or close the fertilizer port 52. The baffle 51 at the outlet of the fertilizer box 5 is used in conjunction with the inertial seeding mechanism 6 to ensure the accurate discharge of liquid fertilizer. Fertilizer channels 615 are provided on both sides of the bottom of the seeding channel 61, which can realize the integration of sowing and fertilization, and reduce the cumbersome process of sowing and fertilization. When the seeding channel 61 moves toward the side close to the groove conveyor belt 3, the baffle 51 moves to close the fertilizer port of the fertilizer box 5. When the seeding channel 61 moves toward the side away from the groove conveyor belt 3, the fertilizer port 52 will be opened, and at this time, the liquid fertilizer enters the fertilizer channel 615 on the outer wall of the seeding channel 61 through the fertilizer port 52.

[0048] In this embodiment, the fertilizer channel 615 and the seeding channel 61 are two relatively independent spaces. The fertilizer channel 615 can be set on both sides of the lower part of the seeding channel 61. The inlet of the fertilizer channel 61 is connected to the feed pipe of the fertilizer port 52 through the fertilizer hose 616. The fertilizer hose 616 can be a telescopic hose. The fertilizer outlet of the fertilizer channel 615 is used to spread the fertilizer around the seed potato cuts to facilitate the increase in yield.

[0049] In order to achieve better results, in this solution, a connecting plate 34 is fixedly provided at the output end of the seed potato groove conveyor 3, and the connecting plate 34 is formed with an inoculation portion 341 extending to one side of the groove conveyor 3, and the inoculation portion 341 is connected to the seed groove 31 for receiving seed potato pieces, and the connecting plate 34 has a space for temporarily storing seed potato pieces, and the two sides of the connecting plate 34 are fixedly connected to the base frame 33. In order to ensure that the seed potato pieces of the connecting plate 34 can smoothly enter the seed discharge channel 61, a clamping and pushing assembly is provided between the connecting plate 34 and the seed discharge channel 61, and the clamping and pushing assembly includes two clamping columns 342 arranged on the end surface of the connecting plate 34 and two clamping columns 342 arranged at the inlet end of the seed discharge channel 61. The potato-pushing elastic sheet 617 is a relatively curved arc structure and is symmetrically arranged on both sides of the inlet of the seeding channel 61. The outer arc surface of the potato-pushing elastic sheet 617 abuts against the clamping column 342. When the seed potatoes reach the tail of the groove conveyor belt 3, they will further enter the upper end surface of the connecting plate 34 and be located between the two potato-pushing elastic sheets 617. The seeding channel 61 moves toward the tail of the groove conveyor belt 3 under the action of the seeding motor. The potato-pushing elastic sheet 617 is deformed under the action of the clamping column 342 to push the seed potatoes into the seeding channel 61. Under the action of the seed-protecting spring plate 613 fixed on the upper inner wall of the seeding channel 61, the seed potatoes are cut into pieces with the right sprout posture unchanged. When the seeding channel 61 moves toward the side of the groove conveyor belt 3, the seed potatoes enter through the openings of the two potato-pushing elastic sheets 617. The potato-pushing elastic sheets 617 are relatively close to each other under the action of the clamping column 342, and the seed potatoes are smoothly pushed into the seeding channel 61.
